dc.description.abstractTaro [Colocasia esculenta (L) Schott] is mainly produced in Africa by small holder farmers and plays an important role in the livelihood of millions of poor people in less developed countries. The genetic diversity of East African taro has not been determined. This study utilizes six microsatellite primers to analyze five populations of taro from three different regions of East Africa. Plant material consisted of 98 taro cultivars obtained from East Africa (Kenya, Tanzania and Uganda). Principal component analysis of microsatellite data indicated variation but did not show any distinct structure. Population diversity estimate was relatively low with the highest being 0.27, for accessions sourced from Lake Victoria basin. Analysis of molecular variance (AMOVA) revealed most variation among individuals within population at 79%. Nei’s genetic distance showed that relatedness is not based on geographical proximity. Based on these findings, this study proposes establishment of a regional collection that will be conserved and ensure a broad genetic base for available varieties and enable development of improved varieties through breeding programmes.en_US
